    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

Removed the second repeat call to make it shorter, as suggested by jylikangas. Used a bolder rectangle character, as suggested by joeytwiddle here: d/9591 #short #default #unicode

If you use 111111111 you get a 3D version with less bytes. :)

Replaced the dot with the "FOUR-PER-EM SPACE" unicode character #short #default #unicode

u/katkip

Oh, thanks
u/jylikangas

Isn't it even shorter without the second repeat call. I mean just adding the vertical parts inside the string
